STATES ROBERT MORRIS, orv WINTHROP, MAINE. Y '.,SPINNima-splNDLE.Y,l

Be it known thatl, ROBERT MORRIs, a citizen of the United States of America, residing at Winthrop, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Spinning-Spin.y dles, of which the following is la s eciiication.

j This invention relates to spin es for spin- Vning machinery, and has for its object the provision of novel means for adjusting the spindle-bearing longitudinally and to afford the bearing. Furthermore, an oject of theinvention is to provide an oil-cup, a whirl, and, in combination therewith, a cap for the oil-cup, so em-l bracin the lowerportion of the whirl as to effectualcly exclude dust from theoil-cup and the bearings of the s indle.

Furthermore, an olij ect of this invention is to provide novel means for retaining the j whirl against displacement and at the same time retaining the. Whirl holding device against accidental displacement.y

It is also an object ofthisinvention to so construct the whirl and the cap that the said cap will effectually hold the whirl against undue movement.

, The invention also provides means ad just-v ed to compensate for the adjustment of the set or stop of the spindle.

Finally, an object of this invention is to produce a device of the character noted possessing advantages in points of simplicity, ef-

ciency, and durability, proving at the same time comparatively inexpensive to produce and maintain.

With the foregoing vand other objects in view the invention consists in the details'of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to theaccompanying drawvmg means. .on the line 3 3 of Fig. 2.

The step C is threaded 'Specication of Letters llatent.V Appiimion filed May 29,1905. serial No. 262.900.

&c. The step C does not form a bearing for the spindle, as` in practice objections are noted Vagainstfa solid step.

It is provided with a transverse groove cin its upper end, in which iits a tongue a, carried by the end of a plug C. The opposi te end of the plug is provided With a recess D, to form a bearin for the spindle E. By this arrangement t v e plug canl be readily replaced if worn without the necessity of applying an entirely new step. This has been found very 'advantageous in ractice, in operation, and economy. The bo ster is further provided with a suitable series of holes G for the purpose of admitting lubricant to the interior,[where the said lubricant may find its way `to ,the bearing of thespindle. The ends ofthe bolster correspond in diame- Iter to the diameterfof the central bore of the casing but intermediately the said bolster is reduced indiameterin order to form the space between the walls of thcCaSing-fand bolster for'the passage of lubricant from the oil-cup or reservoir h. Oppositely-arranged longitudinal grooves H are formed in the upper end of the outer surface of the bolster, extending thereacross. vA longitudinal groove h is formed in the surface of the op osite end of thebolster and is positioned, pre erably, on a plane intermediate or centrally of the plane of the rooves H. A pin e is passed through the bo ster-casing and engages the walls of the groove 71,. This is done to hold the bolster against rotation, a movement liable to occur from friction between the spindle and the bolster in case of lack or exhaust of lubricant. v

The oil within the reservoir H passes through the oriiicel to and within the bolster-` casing A and passing through to theA spindle E. What oil there may be lifted by centriful gal force of the spindle above thebolster F will drop through thel groove H back within the bore of the bolster-casing.

. The oil-cup is preferably formed integral `with the bolster-casing, and the walls thereof are referably thin in order that the capacity of tllfe cup may be large. affords a means of communication between the oilfcup and the interior of the bolster-cas- IOO' A suitable orifice I ing through which the oil from the oil-cup finds its way to the bearing.

The ca N which is provided for the oilcup, fits t e outer surface of the cup, and the IIO upper wall of said cap is thickened to form a guard which surrounds the flange of the whirl and is preferably in light contact therewith to form a joint which would be comparatively dust-proof, yet permitting the free rotation of the spindle. The hole O is formed in the cap for the purpose of permitting the reservoir to be supplied with lubricant, and it is apparent that the inner wall ofthe opening O is below the plane of the end of the flange. The cap N has the lower portion J of its inner surface screw-threaded to engage the threads K of the oil-cup. Within the thickened portionv of the cap is formed an annular shoulder J, which engages a flange L on the lower edge ofthe whirl, and thereby holds the said whirl in position, as will be readily understood from the drawings. It will be seen that when the step C is adjusted within the bolster F the cap N can also be adjusted to compensate for the vertical change of the spindle E.

The central bore of the whirl is of such diameter as to accommodate the upper end of the bolster-casing, and the parts may be so adjusted by reason of the step C as to cause but very light engagement between the end of the bolster-casing and the wall of the whirl, or, if desired, the adjustment may be such as to cause the end of the bolster-casing to clear the middlev of the recess or bore, the said arrangement being such as to permit the adjustments of the elements of the combination to suit particular requirements.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isn

In a device of the character described, a bolster-casing, a bolster therein, said bolster being reduced in diameter intermediate its ends, and being provided with oppositelydisposed apertures near the end of its reduced portion, longitudinal grooves formed through the upper normal portion of the bolster, a sectional step threaded within the bolster,a spindle mounted in the bolster and bearing on the step, an oil-cup formed on the casing, a whirl on the spindle, said whirl einbracing the upper portion of the bolster-casing, a iange formed on the lower edge of the whirl, a cap threaded on the oil-cup, said cap being provided with an inner annular shoulder cngaging the iiange of the whirl, said cap beingr provided with an oriiice communicating with the oil-cup, said orifice being arranged to one side of the shoulder and terminating beneath the flange of the whirl when the device is assembled, and means passing through the bolster-casing engaging the bolster to hold the bolster against rotation within the casing.

In testimony whereof` I aiiix my signature, in the presence of two witnesses, this 23d day of May, 1905.
